Yes, right by analyzing camcontrol devlist it can be told, but i guess not always. [root@qa7 ~]# camcontrol devlist <IFT A16F-G2422 348C> at scbus0 target 0 lun 0 (da0,pass0) <IFT A16F-G2422 348C> at scbus0 target 0 lun 1 (da1,pass1) <IFT A16F-G2422 348C> at scbus0 target 0 lun 2 (da2,pass2) <IFT A16F-G2422 348C> at scbus0 target 0 lun 3 (da3,pass3) Here luns are increasing, so it is SAN confirmed by tool. Now my point is if i have a SAN of less than 1TB and i make only 1 LUN. what should be output? guessing: similar to <IFT A16F-G2422 348C> at scbus0 target 0 lun 0 (da0,pass0) Then it will be difficult to tell, whether it is regular SCSI drives or SAN. Then we need a tool that can tell this da0 belongs to SAN/SCSI or not Thanks Sharad Chandra On Thursday 04 October 2007 6:51 pm, Eric Anderson wrote: > Sharad Chandra wrote: > > Hello, > > > > How to distinguish if /dev/da* devices are internal scsi drivers or LUNs > > of external SAN? > > camcontrol devlist -v > > Might help you.. > > Eric
